Wavelength-stabilized tapered laser diodes in an external talbot cavity: simulations and experiments

Abstract : We present the experimental and theoretical evaluation of the coherent combining of an array of index-guided tapered laser diodes in an external Talbot cavity. A theoretical model taking into account the propagation inside the semiconductor device has been developed to determine the cavity spatial modes. In parallel, experiments have been realized with 10 emitters in a compact setup and a volume Bragg grating as the external mirror. 1.7 W have been obtained at 976 nm for the in-phase mode in a narrow laser line (<0.1 nm).
